ExpressionToCodeLib 2.0.0-alpha9

Generates valid, readable C# from an expression tree, and can annotate that code with runtime values. This can be useful for code generation and for unit testing: ExpressionToCode detects NUnit, xUnit.NET and MSTest and uses their assertions if available, and a normal Exception otherwise (so it runs fine outside those specific unit testing frameworks too). ExpressionToCode was inspired by Power Asssert.NET. It differs from PowerAssert.NET by supporting a much larger portion of the lambda syntax and to respect C#'s normal operator precedence, in addition to general polish.
